As stated above, His being sorry reveals His love for us. What difference would our being good or evil make otherwise.
We are pretty amazing beings - thinking, perceiving, loving, creating, etc. However, in eternity, God felt sorry for this creation since we clearly decided to bring evil into the world from the start.
It is important to remember:
“knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, but with precious blood, as of a lamb unblemished and spotless, the blood of Christ. For He was foreknown before the foundation of the world, but has appeared in these last times for the sake of you who through Him are believers in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God.” (1 Peter 18-21)
Noah, describes perhaps metaphorically the historical reality of what did happen - the beginnings of God’s church on earth: His embracing us, as part of a new Eden in what is the wood of the cross - humanity in right relation with God.
Original sin was washed away then, as it is now in Baptism.
Scripture reveals the changes taking place within the history of mankind, preparing for the eventual incarnation, whereby we are saved and redeemed.
He was sorry for us and He fixed it.
